Abstract

The article presents data on the study of the effect of effective potato rhizobacteria with biofungicidal properties of Bacillus subtilis RT-3 and Bacillus subtilis RT-6 and entomopathogenic nematodes Steinernema filtiae on the background of the use of mineral fertilizers (NP) on microflora, agrochemical composition of soils, and nematode content in potato cultivation. As a result of their application at the beginning of the growing season, before sowing potatoes and by the end of the growing season, positive results were obtained on changing the microbiological, agrochemical, and entomological composition of soils and increasing the number of tubers by 5 pieces on average per 1 plant.
